Carly and Spencer are about to leave their apartment on April Fool's Day because they got evicted by Mr. Bushwell. Sam, Freddie, and Gibby arrive and Carly says that they all had good times in this apartment and remembers one time when they were all siting in the couch watching on TV an episode where the characters were doing flashbacks from past episodes (present in wacky recreations and not actual footage from past episodes). By the end of the episode, Mr. Bushwell comes with Lewbert to tell them to leave the building. Then, Sam asks them to remember that time where they came there and changed their minds about Carly and Spencer leaving, which turns out to be a replay of the scene with Lewbert and Bushwell entering the door. Then, Bushwell lets Carly to stay and Spencer (dressed up as Doc Brown from the Back to the Future films) appears and says he knows the future regarding a "future episode of iCarly" about their kids (Freddie and Carly's or Freddie and Sam's). Then, T-Bo appears inside a giant flying bubble and transports them all in it. They start flying and they come on the camera. The episode ends with the screen saying "April Fools!".

After returning from vacation, Carly falls ill with "Jungle Worms", but feels better after two days, although she is still contagious. Later, Freddie tells Sam, Carly and Gibby that he has received an e-mail from the manager of boyband One Direction (whom Gibby appears to be a massive fan of), saying that they are in the Seattle area and would like to perform a song on iCarly. When they arrive, One Direction perform "What Makes You Beautiful" in the iCarly studio. (Afterwards, Sam takes a liking to Zayn Malik, while Gibby tells Niall Horan and Louis Tomlinson that he gives good foot massages). After Harry Styles drinks from Carly's water bottle, he gets her germs and catches Jungle Worms. Carly takes care of Harry and he is still in bed after a week, much longer than Carly was sick for, making Sam believe that Harry is not actually sick any more and just wants the attention. Liam Payne announces that the boys will have to cancel their shows in San Francisco if Harry is not better soon, so Liam, Zayn, Niall and Louis discuss with Carly, Sam and Freddie what to do to try and get Harry out of bed. Freddie says that Harry might feel better if he thought that he was being kicked out of One Direction and being replaced by Gibby, and when he sees Gibby performing with Liam, Niall, Louis and Zayn, Harry is shocked by how bad Gibby is at singing and dancing and says that he is feeling better, meaning that he was faking. The episode ends with One Direction performing "What Makes You Beautiful" on iCarly. After the song, Sam grabs Zayn by the neck and drags him into the elevator.

After their computer and TV have been stolen, Spencer starts developing a security robot. At first, he builds one that blinds intruders, but takes it apart after it blinds Carly. He then makes one that shoots corn at intruders, but it malfunctions and attacks Carly, Freddie and Spencer. They try to have it focus on Mrs. Benson and unplug it, but Spencer doesn't manage to pull the plug out of the outlet before the machine runs out of corn, so Mrs. Benson is heavily pelted with corn. Meanwhile, Sam and Gibby open a secret restaurant named Gibby's in the basement at school. Bully Billy Boots, who just got out of juvie, harasses and irritates Gibby. Sam tries to diffuse the situation by sending Gibby to go on a walk and trying to talk to Billy, but when Gibby returns later, Billy attacks him and Sam beats up Billy with a Butter sock. The next day, Billy tells Mr. Howard about the restaurant and hopes it gets shut down.

Carly, Sam, and Freddie wonder why people can't celebrate Halloween more than once a year. They decide to celebrate it halfway through the year as well creating a new holiday termed "Halfoween" and have a party. Carly dresses up as a life-size serving of tuna sushi, Sam dresses up with a hat with "hand sanitizer" on it, and Freddie dresses up as Lewbert. Once Nevel finds out, he dresses as a purple robot and give the "iCarly's" candy, which changes their voice and freaks out many people. Because of this, they angrily split up to find out who the purple robot is. Freddie successfully finds Nevel in the iCarly studio. He calls Carly and informs her it was Nevel, but Nevel's friends Ivan and Dimitri force Freddie into the robot costume. Nevel silences him and magnetically seals on the head so Freddie cannot take off the costume. Meanwhile, Sam and Carly get their real voices back, and Freddie probably does too. After Freddie is sent downstairs, he is caught by Gibby and Spencer. Still silenced Freddie is unable to tell his friends that it is him in the costume not Nevel. Subsequently he is suspended and lowered twenty times in Spencer's new game, Jerk Basket, everyone thinking that it is Nevel being punished. After Carly and Sam feel they have their revenge, they realize Nevel was right behind them, happily watching Freddie get jerked. Nevel unlocks Freddie's robot head and they find an angry Freddie. Spencer tries to apologize to him, giving him a free stuffed unicorn from the Jerk Basket, only for Freddie to throw it back at him.

When Freddie gets a new job at the Pear Store, Sam, who is employed with him, accidentally ruins it. Meanwhile, Spencer makes a fire for the 18th time and because of their tiredness, the fire department is done with the Shays and to apologize, Spencer brings a batch of brownies to the station. Unfortunately, the vengeful staff makes him volunteer at the fire station, which leads to another fire, this time at the station. Also, Carly meets a boy at the the Pear Store named Trey and becomes obsessed to get him to ask her out.

After Spencer's arch-nemesis Chuck pulls his latest prank on him and steals his clothes, Spencer finally gets rid of his nemesis by getting Chuck sent to military school. However, this causes Chuck's younger brother Chip to hate Spencer and terrorize him more than Chuck did. Meanwhile, Gibby buys a Galaxy Wars toy phaser and becomes depressed when Sam accidentally breaks it while beating up a bully. Freddie fixes it, but also modifies it into an actually working heat laser gun. During an iCarly webcast, Chip antagonizes everyone with loud music, making it impossible for them to continue. Downstairs, they find Spencer, who has been tied up by Chip. Gibby sets his phaser on "Overload", causing it to overheat. Before it explodes, Spencer throws it down the hallway where Chip is preparing a tub of super glue for another prank. The exploding phaser blows up the tub, and Chip gets thrown back by the explosion and glued to the elevator's doors. When Spencer and the others go to check what happened and find him, Carly says that they can't leave Chip like this. Spencer agrees, then sprays cream on his butt before everyone leaves. Gibby tries to salvage his phaser, but Freddie confirms it's gone beyond repair.
